DEAR MISS MANNERS: My husband and I own and operate a small antique and vintage store in our neighborhood. Our shop is beautifully curated; items are well displayed, clean, and free of defects -- i.e., we are not a secondhand store.

When two ladies were in the store, Lady No. 1 was purchasing four vintage glasses and I commented on her excellent choice. Lady No. 2 asked me, “Can we get a discount?” I offered 10%, which is standard practice. Lady No. 2 said, in a pseudo-hushed tone, “Well, I suppose that is better than nothing,” and called our prices ”very expensive.”

I replied that, in my opinion, she would be hard-pressed to find these at a cheaper price, to which she replied, “Well, I collect this type of glass.” I had nothing nice to say back, so, following my parents’ sage advice, I said nothing further.

I could see that Lady No. 1 was uncomfortable with the exchange, especially when I tried to present her with a receipt after she had specifically told me she did not need or want one (“I have no intention of returning these”).

We do not make any money until the sizable rent, utilities and supplier costs are paid. We purchased most of our inventory many years ago, as we planned to open this shop in our retirement, so our prices are incredibly competitive. These glasses were $10 each, not $100, or anywhere in between.

I, of course, thanked them and wished them both a good day, but I was tempted to chase Lady No. 2 down the street and give her some feedback. I wonder if there might be an acceptable retort if a similar future encounter occurs.

GENTLE READER: It will, and Miss Manners hopes you will continue to restrain yourself.

In antique stores, it is often customary to bargain. You know this, because you offer a discount when asked.

Lady 2’s method of bargaining was unpleasant. The charming way is to praise the coveted object, not to denigrate it, and to plead one’s own constricted budget, not to accuse the seller of greediness. But you should not allow a customer’s coarseness to allow you to become so.

DEAR MISS MANNERS: I have long wondered about the wedding custom of guests applauding after the officiant says the words, “I now pronounce you ______.” Is the marriage ceremony a performance that requires guests to clap?

I have been bothered by this as much as by the intricately choreographed dance performed by the adorable couple. This seems to me to disrupt the atmosphere of a sweet, loving occasion.

I would appreciate your view on these customs.

GENTLE READER: They started as those sweet, loving occasions were evolving into theatrical productions: fanciful bio-epics about the couple, instead of serious religious or civic rituals.

Aside from inflicting amateur theatrics on a captive audience, this approach sacrifices an important emotion. Yes, Miss Manners recognizes the expression of joy and congratulations that the applause is supposed to signify. But there is plenty of room for that to be expressed at the reception.

What is lost is the poignancy that many feel --sometimes to the point of sentimental tears -- at the beauty of the ceremony.

DEAR MISS MANNERS: My close friend, Celeste, is a wonderful cook and hostess who frequently invites me, and mutual friends, over to her home for meals.

While I love Celeste dearly, her fiance makes me incredibly uncomfortable. She has told me stories in which his behavior is emotionally abusive and controlling. I have also had interactions with him at group events and at her dinner parties that have left me feeling more than unsettled.

I have tried approaching dinner party and other invitations with, “Is this a couples’ party or a girl’s night?” and similar lines to assess whether or not he will be joining. I have since learned that he keeps hidden cameras throughout the home, and watches them when he is not there. He also tracks her whereabouts.

Due to this, I have determined that I will not accept any invitations at her home, and his tracking of her has prevented me from inviting her to my home, so we only meet at public places.

Celeste and I have already had a conversation about his abusiveness; however, I am wondering if there is proper etiquette for discussing my hesitation to accept invitations to her home.

I do not want to lose her as a friend, but I believe consistently declining invitations to her home, while accepting invitations to meet at restaurants and coffee shops, may be turning out to be more offensive.

GENTLE READER: Being supportive of your friends does not, Miss Manners assures you, require you to relinquish your own privacy. “You know that I have concerns about your relationship, but as your friend, I will follow your lead. However, I will not be videotaped, or tracked in my own home. So while you are in this relationship, I will have to insist on the two of us meeting in public spaces.”

Your friend will have to make her own decision about the situation, but perhaps the insanity of it can be properly conveyed by seeing it from your perspective. And the accompanying panic in your voice.

DEAR MISS MANNERS: A friend and I have a shared interest in true crime and art. When she recently asked me if I wanted a collage/painting she had made, I said yes, but I was unpleasantly surprised when I received it.

It turned out to be just a canvas with pictures of a murderer on it, and red paint splattered on it to look like blood. It’s honestly creepy; it looks like a shrine to the killer. I’m interested in the psychology behind crime, and have no positive feelings towards killers themselves.

Currently, the canvas is taking up space in my bedroom, not hung up. Would it be terribly rude to get rid of it? One of the things that bothers me most about it is that clearly, very little effort went into it, and it feels like she was just pawning it off on me.

GENTLE READER: Unfortunately, effort is not the only criterion when it comes to evaluating art -- and your friend probably would not take kindly to being accused of lacking it. Miss Manners suggests that you keep the strange painting, displaying it only when your strange friend comes to visit. It might be useful as evidence.

DEAR MISS MANNERS: When my husband and I invite one of our out-of-town friends for dinner, which we do two or three times a year, we always use cloth napkins that go with the tablecloth. Our friend always arrives wearing a thick layer of very bright red lipstick. By the end of dinner, her napkin is covered in lipstick, which is hard to clean. Should we give everyone at the table paper napkins, buy black napkins, or just accept the time spent scrubbing out the lipstick? My husband thinks I am being whiny, but he doesn’t scrub the napkins, although he does a lot of the cooking.

GENTLE READER: There is a reason that restaurants and catering businesses generally use white cloth napkins: They are easier to clean and sanitize with bleach. Miss Manners is not the household hints department, but that sounds reasonable to her.

Paper napkins are flimsy, and black napkins would look strange in contrast to a light-colored tablecloth. They also betray your obvious contempt for a brightly colored lip.

However, if you find yourself still scrubbing and your husband won’t help, it is far better form to accept the loss of the napkin over that of the friend.

DEAR MISS MANNERS: A friend calls at odd hours when I’m not home (but she thinks I am), and does not leave a message. She knows that I can look at my caller ID and see that she called.

When I don’t call her back, she is offended, and thinks I was at home and just didn’t answer her call. I think that since she did not leave a message, then that means she did not need or want to be called back. Am I in the wrong, or should she be leaving a message?

GENTLE READER: Your friend’s method has a one-sided efficiency: requesting a callback without the bothersome task of stating why.

Both parties must agree to this system for it to be effective. In negotiating this agreement, Miss Manners recommends that you warn your friend that without a message, you will not be able to determine the relative urgency of her calls -- and will therefore be forced to assume that they are all low.

DEAR MISS MANNERS: I have two very dear friends who do not know each other, but they both have the very annoying habit of correcting my “mistakes,” such as how I pronounce the name of a foreign city, official or other word.

We have all had at least 16 years of education in this country, in distinctly different areas of study, and yet they are the grammar and culture experts, it seems.

Neither is the kind of person who does this to undermine or to show off, but I am annoyed and offended by their compulsion to correct me. I would never do this to them, but on occasion they have been incorrect in what they said.

Do you have a polite and inoffensive way I could convey my displeasure with their behavior without “correcting” them?

GENTLE READER: Blame a third party. “Funny, I have never heard it pronounced bru-shetta, but I am sure you must be right. Let’s have our waiter settle it. He’s Italian.”
